Abstract

A process for continuously coating a porous substrate to prepare a composite filtration membrane comprises providing a first liquid component and a first applicator means for applying the first liquid component onto the substrate. The first applicator means comprises a slot die head or a direct gravure applicator. A quantitative amount of the first component is applied, onto the substrate to coat the substrate and form a liquid layer, by relatively moving the substrate and the first applicator with respect to each other at a speed of between 20 and 200 feet per minute. A second liquid component is provided and a second applicator means in tandem with the first applicator means for applying the second liquid component The second applicator means comprises a slot die head. A quantitative amount of the second liquid component is applied onto the liquid layer to contact the second liquid component with the liquid layer by relatively moving the substrate coated with the liquid layer and the second applicator with respect to each other. The first and second liquid component is allowed to interfacially polymerize to form a composite layer of a thickness of between about 25 Å and 1 micron. The composite layer is dried to form a composite membrane. Also described is a composite filtration membrane having reverse osmosis properties with the membrane formed from the process described above comprising a composite permeable barrier coating deposited on a microporous substrate. The barrier coating comprises a first layer having a reactant comprising metaphenylenediamine and a second layer having a reactant comprising trimesyol chloride. A composite filtration membrane having nanofiltration properties where the membrane is formed by the above process is also described. The membrane comprises a microporous substrate and a composite permeable barrier where in the barrier coating consists a first layer having a reactant comprising poly(etheyleneimine) and a second layer having a reactant comprising cyanuric chloride An ultra filtration membrane is formed by continuously coating a porous substrate. The process consists of providing a liquid component and an applicator means for applying the liquid component onto the substrate. The component is applied onto the substrate to coat the substrate and form a liquid layer by relatively moving the substrate and the applicator with respect to each other at a rate of between 20 and 200 feet per minute. The layer is then dried to from an ultrafiltration membrane.
